The basics of copper mining and processing mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production using todays compact mining equipment, copper ore is extracted from the mine after the ore is crushed, its roasted, which helps to convert sulfides to oxides
The process used to treat sulfide copper ores begins at the mine site, where the copperbearing minerals are physically separated from the rest of the rock the flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining
Note the green, copperrock vesicles in the ore shown belowthere vesicles were originally bubbles in the lava that have been filled with copper source photograph by randy schaetzl, professor of geography michigan state university commercial ore deposits are present at only about a dozen levels in the portage lake lavas
Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance these are added separately or, as is becoming common, are supplied as blended products to optimize flotation
Phytomining higher tier only phytomining is used to extract copper from soil containing its ore plants are used to absorb metal compounds such as copperii compounds
Copper in the us is used mainly in construction and electric equipment in , the nation produced of the copper it used, relying on imports from chile, canada, peru, and mexico for the remaining copper mining activity increased in the early s because of increased price the price increased from an average of per pound for the year , to per pound for
Native copper was the only source of copper until the turn of the century, when extraction methods were improved the copper ores are far more abundant than native copper, and are the main source of copper today even though, native copper is sometimes mined on its own for the copper content copper ranks second as the mostused metal in the world
Copper is an excellent conductor of electricity most copper mined today is used to conduct electricity mostly as wiring it is also an excellent conductor of heat and is used in cooking utensils, heat sinks, and heat exchangers large amounts are also used to make alloys such as brass copper and zinc and bronze copper, tin, and zinc

Apr , oxidized copper ore bodies may be treated several ways, with hydrometallurgical processes used to treat oxide ores dominated by soluble minerals such as copper carbonate minerals these oxide ores
Even though only of all known copper reserves have been mined, it makes complete sense to conserve the remaining ore for many generations to come conservation of copper ore as weve just stated, the conservation of copper ore is of paramount importance
Data from international copper study group, uS geological survey, mineral commodity summaries, manufacture of copper about of the worlds primary copper comes from ores in which copper is present as a sulfide mineral, for example, chalcopyrite cufes the most abundant copper ore, bornite cu fes and chalcocite cu s these ores contain typically only about

In modern copper smelting, a reverberatory furnace is used concentrated ore and a flux, commonly limestone, are charged into the top, and molten mattea compound of copper, iron, and sulfurand slag are drawn out at the bottom
The use of copper in ancient china dates back to about bc there are ancient copper mines preserved in the mountain of ural where ore used to be mined ago the glaciers of the austrianitalian alps have preserved a skeleton of a man who lived in about bc a copper axe made of , pure metal was found close to him
Jun , typically, copper ores contain only percent copper, so the vast majority is waste you can use a variety of different processes to separate the copper from the waste the exact nature of the refining process depends on which metals and other materials the copper happens to be mixed with and how pure you need the final copper to be
Jul , copper ore is a common resource found in the world it is smelted into copper ingots for further processing obtaining resource acquisiton usage crafting awesome sink see also history copper ore can be harvested by hand default e in trace amounts from resource deposits scattered across the world, or from inexhaustible resource nodes on which miners can be constructed
To smelt quotsulfidequot minerals, that is minerals made of copper, iron, lead and zinc chemically bound to sulfur, it has to be heated and quotoxidizedquot first the more easily smelted ores were exhausted by the time of the fall of rome the moors lived in southern spain during the middle ages they used copper for cooking utensils and for ornaments

Jan , for this paper, only the direct smelting of copper ore has been considered the composition assumed for the copper ore was chalcocite , pyrite and quartz the processing conditions obtained from the mpe model were then incorporated into a simulation model of the process set up using the commercial process flowsheeting
Copper mines are only set up where there is more than kg of copper per tonne of rock by mass ideally, the figure should be closer to the worlds largest copper ore deposits are found in chile on the west coast of south america this is due to the volcanic activity that is part of the process that created the andes mountain chain
There are two main types of reactions used for extracting copper form its ore in one reaction, copper oxides reduced by carbon to produce carbon dioxide and pure copper
